Claims

[Claims for Utility Model Registration] (1) A locking pin that locks the other end of a torsion spring whose one end is locked at a predetermined position; angular displacement driving means for angularly displacing the locking pin around an axis parallel to the longitudinal direction at a position shifted from the locking position with the other end; and linearly displacing the locking pin in the axial direction of the locking pin. and a linear displacement drive means for moving the spring by the torsion spring while displacing the other end in one direction along the axis of the locking pin while the other end of the torsion spring is locked by the locking pin. When the other end is angularly displaced in the opposite direction to the biased direction and passes the locking protrusion at the predetermined locking position, the locking pin is moved to the locking protrusion side. The angular displacement driving means and the linear displacement driving means are operated so that the locking pin is displaced in a direction opposite to the one direction of the axis, and then angularly displaced in a direction in which the locking pin is biased by a torsion spring. Torsion spring mounting machine. (2) Utility model registration claim 1, characterized in that the linear drive means is realized by a cam.
Torsion spring mounting machine as described in section.
